(Round the lethod is $ On January 1, Questor Trucking purchased a used Kenworth truck at a cost of $48,000. Questor Trucking expects the truck to remain useful for four years (700,000 miles) and to have a residual value of $6,000. Questor Trucking expects the truck to be driven 140,000 miles the first year and 245,000 miles the second year. Read the requirements Requirement 1. Compute Questor Trucking's first-year depreciation expense on the truck using (a) Straight-line, (b) Units of production, and (c) Double-declining balance. Start by selecting the formulas needed to compute annual depreciation under each of the three methods. Straight-line depreciation = Units of production depreciation = Double-declining balance depreciation a. Compute Questor Trucking's first-year depreciation expense on the truck using the straight-line method. First-year depreciation on the truck using the straight-line method is $ b. Compute Questor Trucking's first-year depreciation expense on the truck using the units of production method. (Round the depreciation per unit to the nearest cent, and round your final answer to the nearest whole dollar.) First-year depreciation on the truck using the units of production method is $ D . C. Compute Questor Trucking's first-year depreciation expense on the truck using the double-declining balance method. (Round the double-declining depreciation rate to two decimal places. Round your final answer to the nearest whole dollar.) First-year depreciation on the truck using the double-declining balance method is $ Requirement 2. Show the truck's book value at the end of the first year under the straight-line method. Select the formula and then enter the amounts to calculate the book value at the end of the first year using the straight-line method. = Book value
